The Hellfire Club had Krakoa attack the school. When this happened, Kid Omega accessed his mind and discovered his origins. He had Krakoa open up to Marvel Girl, who relayed his apologies to Headmaster Wolverine. Krakoa told her that he was a mutant and asked to join the X-Men. He was allowed to stay as Logan found it good to have a school grounds which can fight back.[1]

Krakoa was the solution for the school's money woes, as he could grow diamonds on trees.[3]
